Subject: [PATCH 34/35] qed: Add cleanup in qed_slowpath_start()
Git-commit: de0e4fd2f07ce3bbdb69dfb8d9426b7227451b69
Patch-mainline: v5.3-rc7
References: git-fixes
If qed_mcp_send_drv_version() fails, no cleanup is executed, leading to
memory leaks. To fix this issue, introduce the label 'err4' to perform the
cleanup work before returning the error.
